VIBRATION-RECORDER.

" .To an whdm it may concern."

. Be it known that I HANS SATTLER a citizen of the United states, and resident of Sheboygan, in the county ofSheboygan and State of Wisconsin, have invented certain new and useful Improvements in-Vibration- Recorders; and I do hereby declare that the following is a 'full, clear,-and exact descrip;

tion thereof. 1

useful improvements in vibration recorders automatically recordin movement of automobiles, and other vehicles or moving bodies, by actuation of certain' mechanism from vibrations of the ve The primary object o 'my invention is 10 My invention relates to certain new and I hicle or bodyduring h tie; in

' the provision'of such a devlce which will record of the operation or travel of. the vehicle for a certain period of time, as for give the owner. of a vehicle a complete ---marker 20vtotrack and're cord the fibr tions, the. plate 16. is made smaller inidiaminstance twenty-four hours, andin this way allowing the owner to ascertain whether ornot the driver has been. unlawfully using 7 such vehicle.

With the above and otheriobjects-in view which will appear 1 as the description pro-j.

. ceeds, the invention resides in the novel construction, combination andjarrangement of parts hereinafter described and then sought to be clearly defined by the claims, it being ,For working the stylus 20 to record the can be made withoutdeparting from the."

ing the spring 9 and the connection of the gears wlth the dial plate, a further des'cription is thought unnecessary.

. Secured 'to the top member of the frame 7 is the arm 10 which has formed on one (not shown) injsaid sleeve to engage "the arbor aswill be readily .seen'i=-byreference to Fig. 2.

.The outer end of the sleeve 11 is threaded. j 1

to receive a nut 13 which revolubly retains 1 on said sleeve the bushing 14 secured to which by suitablefastenings 15 is the plate -Q 16, and between thiswplate and the dial plate 17, is secured the record-receiving'dial I said dial plate'17 with dial '18-is held; 1n placeby the nut 13 bearing. against the collar 19. In'order'to allow} a space on the record-receiving I dial (for. the stylus or eter than the plate 17 and dial-18, the-con;

,vibra tions I- employ" a novel 'formof bal- "fanced endulum 21. which is pivoted at 22 the orked bearing 23 secured to the base 5 by any suitable fastenings 24. This pendulum is formed with the two arms 25 and physical embodiment of my invention 0011- ot the principles of my invention.

so far devised for the practical; application 45- Fig. 2 is a view partly in section '26, the arm 25 being; formed with an entherein the threaded end'28ofithe'stylus receiving pocket 29, having the light'spring receivin dial 18.

or vibration, a spiral spring 31 is employed, one end of which'is secured to the arm 26 largedportion acting .as a balancing weight, and the arm 26" having secured ,so 1' 'struction and .operation of the stylils 20 be in hereinafter described. I 1

In or or to control or to'returnthe pen I dulum to normal position after each shock .Fig. 3 'is a view with parts in section at 32 and the other end of whichis secured to the eye '33 of the adjusting screw 34, secured in the post 35 secured to the supporting base 5, a locln'ng nut 36 being employed -to lock the adjusting screw 34 in the desired adjustmen It will be understood a sassin 18 is divided into hours or any other desired divisions, and that when the body to which my device is attached is standing still the stylus 20 will record an unbroken line upon the revolving dial 18, but when the body is in motion the stylus will record a jagged or broken line as the pendulum is vibrated by the shocks or vibrations caused by the movement of the body.

While I have mentionedmy device as for use in keeping record of the movements of vehicles, it may be used in testing the efiicienoy of shock absorbers or the like, by first running a vehicle not equipped with shock absorbers over a road and then running the same vehicle over the same road after it has been equipped with such absorbers, and then comparing the two records obtained by in device, as will be apparent to those skil ed in the art to which an invention of this character appertains.

What is claimed is:

1. In a vibration recorder, the combination with a continuously revolving record receiving dial and its operating mechanism and supporting base therefor, of a forked bearing secured to .the base, a pendulum pivota 1y. mounted in said bearing, said pendulum being bent to form an obtuse angle and having one of its arms weighted, a st lus carried by the other arm of the pen ulum and bearin on the dial to record the'vibrations of the ody to which the recorder is attached, and'spring means connecting the arm carrying the stylus and the supporting base for the purpose described.

2. In a vibration recorder, the combination with a continuously revolving record receiving dial and its operating mechanism and supporting base therefor, of a pendulum open to form an obtuse angle and ivotally supported from the supporting ase at the apex of the angle, one arm of the angle being longer than the other said longer arm bein weighted, a stylus carried by the shorter o the arms and bearing upon the record receiving dial to record the vibrations of the body to which the recorder is attached, and spring means connected with the outer end of the shorter arm and supportin base to govern the movement of the pendu um, substantially as described.

3. In a device of the character described, the combination with a continuously revolving record-receiving dial and its operating mechanism and supportin base therefor, of a bearing secured to sai supporting base .formed by a base plate having a laterally and then upwardly extendin arm carried thereby, a pendulum open to orm an obtuse angle and having its apex givotally secured in the forked end of said caring, one arm of the pendulum being longer than the other, said longer arm being weighted and extending downwardly at an incline and said shorter arm extending outwardly from said bearin on a substantially horizontal plane, a soc et formed in the outer free end of said shorter arm, a stylus carried by said socket and being resiliently urged against the record-receiving dial to record the vibrations of the body to which the recorder is attached, and an adjustable spring connected with the outer end of the shorter arm and with said supporting base for returning the pendulum to normal position after each vibration thereof substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of .Milwaukee and State of Wisconsin.

HANS SATTLER.
